In any event, I have always found the old TA bb parts to be beautifully made from very nice and durable materials. I always use loose balls with TA, and you can get them adjusted to turn with such a small amount of friction. It is probably purely psychological, but I think that the TA Tevano parts may have been machined to an even higher tolerance than the standard branded ones. The spindle numbers are the same to ease in searching for the right parts. As a pure bonus, not a lot of people look for Tevano so you may even be able to find them at a bargain…The original numbers produced were much lower than the standard units, though….
